Just to expand on this somewhat; Renamon and Werewolf are different forms I shift into depending on how I'm feeling.
If I'm in a mood where I'm feeling nice about my appearance, maybe kinda playful/sexy, that's when I'm Renamon
If I'm in a (good) mood where I'm kinda head strong, bitey and snarly, eager and all "HECK YEAH!!" that's when I'm Werewolf.
For shift triggers the moon does play into it but more so I'm Renamon when around a few friends and Werewolf when I'm around a "pack" of friends.
Also had a bit of a personal canon think the other day!
I started out as a human werewolf, but an encounter with a faulty D-Ark (digivice from Digimon Tamers) permanently overwrote my human form with Renamon data, leaving the werewolf side unaffected and still accessible by me, no shift triggers affected. :3
I've always kinda liked three big digits on things; maybe it's a Renamon thing, or a creature suit thing.
Either way this is giving me a lot of thinks. >.>
@renbymon three big digits are very yes >.>
